If you have plenty of runway, this is easier on the brakes, engines, and fuel burn. And gets you out quicker for that plane landing behind you.

OTOH, when the smart pilot needs every foot of runway, you taxi out the the paint stripe and stop. The engines are run up to full power and the pilot has a couple seconds to see all engines are at full power before releasing the brakes. This is hard on the brakes, hard on the engines, and burns an extra 1000 pounds of fuel, but when it needs to be done, the smart pilot does it. Lets you know a safe pilot is running your flight.^ Whan deplaning, tell the Captain "You da Man", as you just flew with the pilot you want on every flight.^ ^ ^ ^ ^
